if the traffic is a nice steady drone at different frequencies to the wildlife, you may be able to simply filter out the offending frequencies, but you'll probably lose some fidelity in the wildlife sound.
If you have some money to spare, you could also look at noise reduction software, e.g http://www.sonycreativesoftware.com/noisereduction, which works nicely with Vegas and has been a lifesaver for me on several occasions when I've had bad location sound. For a one-off cleanup, the trial version (time-limited but otherwsie fully functional, I think) may be enough for you. It's possible it isn't Vegas 6 compatible, but I'm pretty sure it will work.
